    As you probably know, two masses pull on each other, rather than just the big one pulling on the little one. The moon causes the tides, but these bulges are not in line with the moon. There is a lag. So those slight, off-center tidal bulges on the earth, pull back on the moon just a little bit. This changes the moon's speed, but at an exceedingly slow rate and only noticeably over tens of millions of years.

    Edit: Er, geez, I saw the answer below me. Is that all you wanted to know?

    The rotation makes the moon appear to rise in the East and set in the West every day.
